RETAINING-CLIP FOB: FOUNTAIN-PENS.

Specification of Letters Patent.

Patented Dec. 18, 191 7.

Application filed March 29, 1917. Serial No. 158,370.

To all whom it may concern:

Be it known that I, LEVI D. VAN VALKEN- BURG, a. citizen of the UnitedStates of America, and resident of Holyoke in the county of Hampden andState of Massachusetts, have invented certain new and useful 1Improvements in Retaining-Ch s for Fountain-Pens, of which the followingis a full clear, and exact description.

This invention relates to improvements in retaining clips moreparticularly to be employed on the caps or barrels of fountain pens, andhaving unusual availability for employment on self filling fountainpens.

The objects of the invention are to so construct the means for theattachment of the retaining clip on the cap or barrel of the fountainpen as to provide a simple, inexpensive and efficient connecting means,one that is readily applied and which may be easily disconnectedwhenever desired, and one which is in no way obtrusive or unsightly whenpresent on the pen.

And a further object is to so construct the retaining clip withreference to the single device which connects it on the fountain penthat the conjoint parts. are prevented from swinging or relativerevoluble movements.

The invention is described in conjunction with the accompanying drawingsand is set forth in the claims.

In the drawings Figure 1 is a side elevation showing the cap member of afountain pen and a clip represented as secured on and along the sidethereof.

Fig. 2 is a longitudinal vertical section as taken on line 2-2, Fig. 1.

Fig. 3 is a view similar to Fig. 2, illustrative of this invention, butshowing parts included therein, in reversed relations as may manifestlybe done without departure from the essentials thereof.

Fig. 411s across sectional view as taken On line 44, Fig. 1.

Figs. 5 and 6 are respectively a side elevation of an element employedin the device and across sectional v1ew as taken on line 6-6, Fig. 5. Iv

In the drawings, A represents the cap member of a fountain pen having atransverse hole a therethrough, different portions of which are ofdifferent diameters as shown.

B and C represent a pair of members to be inserted through thetransverse hole, one thereof having an inwardly opening screw threadedbore 6 therein, and the other bemg n the form of a threaded stud or pinto engage in said bore.

0 represents a retaining clip for the'fountaln pen, whlch may be made ofthin metal, and the shank portion of which is cross sectionally of are,or concavo-convex form to correspond to the rounded surface of the capor barrel of the fountain pen and havmg spurs d d for engagement with,or penetration into, the portion of thepen on which the clip is applied.

'As shown in Fig. 2, the screw threaded pin or stud is represented asthe confining member for the cllp, the same having a head enlargement fwhich engages and holds the clip on the pen, while in Fig. 3, the memberC having the threaded hore and a flat head or enlargement g is theelement which holds the clip in its confinement on the pen.

Preferably constructed, the device as represented in Figs. 2, 4 and 6the screw threaded stud B has the portion thereof near 1ts outer end ofnon-circular form, as represented at h,such form being especially asrepresented, cross sectionally in Fig. 6, and as may be produced byslabbing the opposite sides of the stud, and the aperture in the clip isto be of corresponding form.

This provides that there may be no swingmg or revoluble movement of thepen clip and stud, either relatively to the other,the spurs of the clipcontributing in conjunction with the other features to this advantage.

The last mentioned feature of construction is practicable in practiceand assemblage, as the slabbing oif at the outer end portion of the studmay be performed entirely to the outer end thereof, permitting theengagement of the clip and stud whereupon the protruding extremity ofthe stud may be upset to overlie the outer surface of the clip.

The parts so produced may be brought to their engagements on the pen asrepresented in the drawings, the spurs engaging as shown, whereupon thesleeve-like member, the head of which is slotted, may be pushed into theperforation therefor in the opposite side of the pen cap and barrel andproperly turned, when brought to screw engagement with the threaded studfor firmly binding the stud in the maximum inward position thereof andfor clamping the clip on the pen.

As shown, Figs. 2 and 4, the head of the sleeve-like and internallythreaded member has its disposition within a countersunk outer end ofthe perforation in which it 1s positioned whereby it forms norotuberance on the side of the pen, and y bemg colored, properlycorresponding to the color of the pen, may be practically invisible, orat most will not be obtruslve to the eye, or in any way unsightly.

It will be manifest from inspection of the drawings, that these devicesfor the retention of the clips on the ca s or barrels of fountain pensare as wel applicable on fountain pen members of comparatively smalldiameters as upon those of considerably greater diameter.

I claim 1. In a device of the character described, the combination witha fountain pen cap having a transverse hole therethrough, of a pair ofmembers to be inserted through the transverse hole, one thereof havingan inwardly opening screw threaded bore therein and the other being inthe form of a threaded stud or pin to engage in said bore,one of saidmembers having a pen-retaining clip engaged therewith at the outer endthereof, and confined thereby on and along the side of the cap, and theother of said members having a head enlargement for engaging the side ofthe cap, and means for the rotation of one of the members. I

2. In a device of the character described, the combination with afountain pen cap having a transverse hole therethrough, of a pair ofmembers to be inserted through the transverse hole, one thereof havingan inwardly opening screw threaded bore therein and the other being inthe form of a threaded stud or pin to engage in said bore,one of saidmembers having apenretaining clip engaged therewith at the outer endthereof, and confined thereby on and along the side of the cap, and theother of said members having a head enlargement for engaging the side ofthe cap, means for the rotation of one of the members, and said penretaining clip having inwardly extendmg spurs for engagements with thewall of the cap.

3. In the combination with a fountain pen cap a device of the characterdescribed,

having a transverse hole therethrough, of a pair of members to beinserted-through the transverse hole, one thereof having an inwardlyopening screw threaded bore therein and the other being in the form of athreaded stud or pin to engage in said bore, a pen retaining clip, theshank portion of which is of thin metal cross sectionally of concavoconvex form to conform to the rounded surface of the cap and havingspurs for engaging the cap which clip is engaged with one of the mem ersat the outer end thereof and confined thereby on the side of the cap andthe other of said members having ahead enlargement for engaging the sideof the cap, and means for the rotation thereof.

4. In a device of the character described, the combination with afountain pen cap having a small transverse hole therethrough, of a studhaving a screw threaded inner end portion and a sleeve-like memberhaving the bore thereof opening inwardly and internally screwthreaded,and provided with a.

head, both being inserted in the said hole and having screw threadengagements, one within the other, a clip with the shank portion ofwhich the said stud has an engagement for confining it on the side ofthe cap through means of a head enlargement on the outer end thereof.

5. The combination with a fountain pen cap havlng a transverse holetherethrough,

of a pen retaining clip, the shank of which is-fprovided with anon-circular aperture therein, a screw threaded stud having a portionthereof near its outer end of noncircular form to engage through thecorrespondingly shaped aperture of the clip and having its outer endupset against the outer surface of the clip, and a sleeve-like memberhaving the bore thereof internally screw threaded and provided at itsouter end with a slotted head enlargement,the stud and sleeve-likemember being inserted in the aforesaid transverse hole in the cap andhavin screw thread engagements onewith the ot er.
